The paper addresses the problem of visual tracking in low-power visual sensor networks. Accurate real-time localization and energy efficiency are key issues in such applications. A novel approach for tracking and identification of robots using 1D barcodes is proposed. The nodes in the network perform visual processing and export processed information in… (More)

The demonstrator addresses the problem of localising a transmitter using time difference of arrival (TDOA) between pairs of nodes in a Long Range (LoRa) wireless sensor network (WSN). The proposed frequency counter scheme is able to timestamp multiple incoming LoRa (burst) transmissions in an effort to accurately determine the difference in arrival across… (More)
